Sigma 4.5mm f/2.8 EX DC HSM Circular Fisheye Lens for Sony A
Key Features
  • A-Mount Lens/APS-C Format
  • 6.75mm (35mm Equivalent)
  • Aperture Range: f/2.8 to f/22

Offering creative distortion and exaggerated perspectives, the Sony A-mount 4.5mm f/2.8 EX DC HSM Circular Fisheye from Sigma produces a circular image with an expansive 180° angle of view. Benefitting the unique look of the lens is an advanced optical design that utilizes one SLD glass element to reduce color fringing and chromatic aberrations for improved clarity.

Additionally, the lens also features a Hyper Sonic Motor for quick and accurate autofocus performance for working with subjects as close as 5.3" away.

question

Does this lens have front filter threads? If so what size? A reviewer has mentioned that this lens can be used with front filters despite the protruding front element.
Asked by: Anonymous
The lens itself, like virtually any fisheye lens, does not have filter threads. This is a matter of the physics in the designing such lenses. The reviewer mentioned that this Sigma Cap Adapter for a Sigma 4.5mm f/2.8 B&H # SICA48672 allows a 72mm filter or lens cap to be mounted. If you go this way, watch out for filter vignetting.

question

Will an a77ii produce a fisheye effect with this lens?
Asked by: Timothy
Thank you for your interest in Sigma products. Two things that you need to keep in mind. 1- This is a Sony A-mount lens and you 'll need an adapter to use this lens on your Sony A7 (E-mount) camera. 2- This is a DC lens and it's designed to create a circular picture for APS-C size sensor. for your Full-frame camera, I recommend the Sigma DG 8mm Circular Fisheye (which projects a larger circle for larger sensors) withe proper adapter for E-mount): https://<a href= http://www.bhphotovideo.com/c/product/440665-REG/Sigma_485101_8mm_f_3_5_EX_DG.html?sts=pi target= _blank >www.bhphotovideo.com/c/product/440665-REG/Sigma_485101_8mm_f_3_5_EX_DG.html?sts=pi</a>

How will this work with a Panasonic AG AF100?
Asked by: Anonymous
This lens will not be compatible with the AF100 without an adapter as the mount is EF. A MFT to EF adapter would be needed.

What is the part # for the rear lens cap?
Asked by: Anonymous
Sorry to say I do not know that part number! But, that end-cap is exactly the same as all other Canon EOS digital lens rear caps. Any should fit (if what you need is to replace one), so...
